Diagnostic Testing for Laryngopharyngeal Reflux Disease: The Role of 24-hour Hypopharyngeal-Esophageal Multichannel Intraluminal Impedance-pH Monitoring.

Laryngopharyngeal reflux disease (LPRD) presents as a constellation of nonspecific upper aerodigestive tract symptoms and signs. Among many objective tools available on the market, hypopharyngeal-esophageal multichannel intraluminal impedance and pH monitoring (HEMII-pH) is considered to date the gold standard technique for diagnosing LPRD, as well as tailoring treatment according to the different LPR profiles. More studies are needed to further validate and standardize diagnostic criteria and evaluate long-term outcomes of patients diagnosed and treated for LPRD using HEMII-pH.
